Qualcomm SOCs have a secure remote processor that provides secure execution environment for processing sensitive data and also performs cryptographic operations using protected keys stored in its secure storage. This patch series introduces a Peripheral Authentication based remoteproc driver that handles booting, shutdown and crash scenarios for SPSS. Also this driver can handle late attach usecase where remote processor is already booted even before linux. This patchset builds up on the skip firmware load patch "remoteproc: add support to skip firmware load when recovery" which is in review.
